What is the difference between a glass chandelier and a crystal chandelier?

The difference between a glass chandelier and a crystal chandelier is in the materials used to produce the light fixtures. Glass chandeliers are made of glass, a hard, brittle material made by melting together a combination of substances, such as sand, soda ash and limestone. When you add lead to these ingredients, you get crystal, a heavier material that can produce a reflective, sparkling effect when cut.
